Matt Barnes has a little unfinished business with the Sacramento Kings.

Barnes was free to rejoin the Golden State Warriors in February because he was released by the Kings following their DeMarcus Cousins trade, and being dumped by his hometown team didn’t sit well with the hot-headed NBA veteran.

Threats of violence — hyperbole or not — is not a good look for Barnes, who infamously attacked then-Knicks coach Derek Fisher in a jealous rage and is facing assault charges in New York City after allegedly choking a woman and punching her boyfriend in a nightclub melee last December.

You’d think Barnes might be a bit less vengeful and a bit more excited about having a legitimate shot at winning a title just down the road in Oakland. Indeed, Barnes’ trial in New York was postponed until late June after his lawyer argued Barnes likely would be occupied by the NBA Finals until then.
